Mikc, I don't know anything about your Grandpa James but you and I have to ber elated on the Halker side. My grandfather was Leonard J. Halker, born in Glandorf, Ohio in the late 1800s. Many of his family resided in the surrounding areas. I have an obituary for him that lists siblings of his - any of which could be a great (or otherwise) grandfather of yours.
